Definitions

  • This invention relates in general to power transformers and more particularly to power transformers of the type used with power supplies found in different regions of the world.
  • Power transformers are used to convert an alternating current power supply of the type available in homes, offices, hotels, and the like, via an ordinary wall outlet, to a direct current power supply compatible with electronic devices. These power transformers are used to reduce dependence upon batteries, or to provide charging energy for rechargeable batteries from available alternating current power sources.
  • the transformer includes a power converting circuit within the housing having a male connector positioned thereon. The male connector is for connection to a female connector of a main power supply wall outlet.
  • a difficulty encountered by international travellers is powering their electronic equipment from the main power supplies found in different regions of the world. This difficulty arises because power supplies in different countries have different voltages, currents, and supply frequency characteristics. They also have different wall outlet female connector configurations. Although power converter circuits have been developed which produce a regulated direct current voltage from most main power supply signals found throughout the world, accommodating different female connectors have been more difficult. Therefore, there is a need for an improved international power transformer adapter transfiguration.
  • US patent no. 5,628,641 disclose a collapsible plug device having a rotatible plug having two pins.
  • the present invention is a plug prong comprising a blade and an anchor.
  • the blade has a section cut from one or both sides, and the cut-out section is replaced by plastic.
  • the anchor of the plug prong is covered by plastic except for an electrical contact area.
  • the plug (also called power supplies and power transformers) prong of the present invention may be used advantageously in adapter plugs where the plug prongs rotate from a position flush or below the face of the adapter plug housing to a position where the prongs jut outwardly from the face of the housing.
  • the plastic replacing one or two sections of the blade, and covering the base of the blade helps to prevent children from being shocked when they try to touch the prongs of the plug when it is inserted into a wall outlet. Since the plastic only covers the anchor of the prong, and sections of the sides, it does not inhibit the proper electrical contact between the distal end of the prong and interfere with the female electrical connector in the wall outlet.
  • FIG. 1 shows the plug prong of the present invention before it is partially covered in plastic.
  • FIG. 1 shows the plug prong (10) of the present invention. Shown is blade (20) with sections (50) cut out along the side of the blade.
  • FIG. 2 shows prong (10) of the present invention. The sections (50) cut out along the sides of the blade (20) have been replaced by plastic (60).
  • the plastic (120) also covers the anchor (30) of the prong (10), except for electrical contact area (40). In this embodiment, the sections (50) cut out along the side of the blade (20) extend from the anchor (30) to about halfway up the blade (20).
  • FIG. 3 shows the prong (10) of the present invention employed with an adapter plug with a rotating set of prongs (10).
  • An adapter plug with a rotating set of plug prongs is described, for example, in U.S. Patent No. 5,613,863 entitled "Power Transformer,” inventors T. R. Klaus, et al, assigned to Motorola, Inc.
  • plug prongs (10) rotate between position "A” jutting out from the face (130) of the adapter housing (100) and position "B” below the surface of the face (130) of the adapter housing (100).
  • a child's finger or a paper clip could insert itself into the recess (80) of the adapter housing (100) and touch a live section of prong (10).
  • FIG. 4 shows a flip plug (70) employing the prongs (10) of the present invention used with a variety of international plug adapter configurations 990).
  • prong 10 is rotated into a position below the surface of the face (130) of the adapter plug, and international adapter plugs (90) are slid over the prongs (10). Since the plastic inserts (60) occupy the same volume as the section (50) cut out along side the blade, international adapter plug (90) can be slid over the prong (10) of the present invention, as easily as they can be slid along standard prongs.
  • Plastic inserts (60) and plastic coating (120) around the anchor may be formed, for example, by injection molding. Any suitably durable, insulating plastic may be used.
